More Information

No
The device description and performance studies focus on standard centrifugal technology and optical readout, with no mention of AI, ML, or related concepts.

No
The device is a micro hematocrit centrifuge, used to measure hematocrit (a diagnostic measurement), not to treat or prevent a disease or condition.

Yes.

The device measures hematocrit, which is a key diagnostic indicator for various medical conditions, and comparative studies show its clinical utility is equivalent to a predicate diagnostic device.

No

The device description clearly outlines hardware components such as a centrifuge, battery charger, and physical safety features, indicating it is a physical medical device with potentially embedded software for the digital readout.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Measures Hematocrit: The device description explicitly states that it "Measures Hematocrit." Hematocrit is a measure of the volume percentage of red blood cells in blood, which is a diagnostic parameter.
  • Uses Micro Capillary/Micro Capillary Holders (heparinized): This indicates that the device is designed to process blood samples, which is a key characteristic of IVD devices.
  • Intended User / Care Setting: The intended users and settings (General Laboratory, Physician Office, Blood Bank) are typical environments where in vitro diagnostic testing is performed.
  • Performance Studies: The document includes performance studies comparing the device to a predicate device and evaluating precision, which are standard requirements for demonstrating the performance of an IVD device.
  • Predicate Device(s): The listed predicate devices (Compur MI100 Minicentrifuge, Compur Millo Hematocrit System) are also devices used for measuring hematocrit, further supporting the classification as an IVD.

While the "Intended Use / Indications for Use" section is listed as "Not Found" in the provided text, the other information strongly indicates that this device is intended for in vitro diagnostic use. It performs a measurement on a biological sample (blood) to provide information for diagnostic purposes (hematocrit).

Comparative data (Performance/Effectiveness Information) between the Spuncrit (Model DRC-40) and Compur's MILO Minicentrifuge.
An "In Service" to explain the operation of the Spuncrit was performed in each of the locations. Approximately 10 minutes were utilized for training of persons operating the Spunctic a nhe comparative study at each location included a total of 45 whole blood samples encompassing three levels ranging from below the normal range to the upper level of the normal range . The samples were split such that each location ran 15 samples at each level.

§ 864.6400 Hematocrit measuring device.

(a)
Identification. A hematocrit measuring device is a system consisting of instruments, tubes, racks, and a sealer and a holder. The device is used to measure the packed red cell volume in blood to determine whether the patient's total red cell volume is normal or abnormal. Abnormal states include anemia (an abnormally low total red cell volume) and erythrocytosis (an abnormally high total red cell mass). The packed red cell volume is produced by centrifuging a given volume of blood.(b)
Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 864.9.
